I don't think the issue is whether Trump/Clinton will initiate a nuclear confrontation directly. The question is whether either of them have the qualities it takes to stand down if/when the US is attacked by an insignificant foe, rather than retaliating against someone with nukes.
Frankly, I don't think they are any different in that regard. Neither would be willing to accept the responsibility of being impeached/etc in order to avoid a larger confrontation. Second term Obama on the other hand probably would, I think he has changed in that regard. I say that because he seems to be doing a fine job of realizing that we can't solve the Syrian problem with more guns/bombs. See Libya, etc...
